I've decided to build a simple, adjustable bench PSU unit to power my little projects at home.
To keep things rather simple, I decided to build it around the LM2576-ADJ step down switching voltage regulator from TI.
I have breadboarded the circuit and it works fine, the only issue I'm having is that when I turn the potentiometer to lower the voltage on the output, the voltage is taking some time to drop down...
Here is my complete circuit:
I think the issue must be coming from one of the caps on the output (C2 or C3). They must be holding energy and taking some time to discharge and that is what's causing the voltage to drop slowly on the output.
Is there any technique o circuit I can use so that the caps discharge quicker when I want to lower the voltage?
